Police in Germany caught Anders Breivik with ammunition and weapon parts in 2009, two years before he killed nearly 80 people in Norway, but did not arrest him and failed to notify Norwegian police, according to a new documentary. Breivik is a jailed far-right terrorist, who in 2011 single-handedly perpetrated two terrorist attacks that killed 8 people in Norwegian capital Oslo and another 69 on the island of Utøya. During his trial, he said he killed his victims, most of whom were participants at a Norwegian Labor Party summer camp, in order to protest against “multi-culturalism” and “Islamization” in Norway. The attack, which included the use of a car bomb and semi-automatic weapons, is considered the deadliest terrorist incident in Norway’s history since World War II.

Last week, however, a new documentary aired on Franco-German television station ARTE claimed that German police could have helped stop Breivik’s deadly plans, when it caught the far-right militant with weapons parts and ammunition in 2009. The documentary, entitled Waffen für den Terror (Weapons for Terror) was directed by Daniel Harrich, a German documentary filmmaker who specializes in the international illicit weapons trade. Harrich alleges in his documentary that Breivik was stopped “in early 2009” by German police during a routine check in Wetzlar, a city of 60,000 located just north of Frankfurt.

Citing three unnamed sources, who allegedly verified the claims independently of each other, Harrich said that Breivik was found to be in possession of ammunition and was also carrying some weapons parts. But instead of detaining Breivik, who was carrying a Norwegian passport, and notifying the authorities in Oslo, the German police officers simply confiscated the ammunition and some weapons parts, before allowing him to go. According to Harrich, Breivik was even told he could hold on to a number of parts that German police determined could not be used to build a working weapon. Harrich’s documentary, which is in the German language, can be viewed at ARTE’s website, here.
